@Mohit,

In Argument scientiests say that a fish can either be shark or eel so it is already given in the argument that fish cannot be both shark and eel. So E can be eliminated.

There are some constrats confusing the scientists thats why they are unsure on the exact type of fish. Read the facts above:
1. Because of the habitat where it was found and its obviously eel-like body, almost all scientists believe that the fish is an eel.
2. [Counter premise] But the cartilaginous skeleton puzzles them, since no known eel possesses one.
3. So scientists are still unsure as to the fish's precise classification, but they agreed immediately that the most logical classification would be as either a shark or an eel.

The ending of conclusion rules out E.
E. A fish cannot be both a shark and an eel.

I doubt whether the stimulus confirms the fish as eel or shark, for certainity.
But, except D none is suitable as per the context. There is no mention/indication on:
1. Fighting among fish
2. Fish survival

So, only D survives.

Answer D may fall apart by the following explanation, I provided:

D. The waters off Papua New Guinea are generally hospitable to eels.
I did not take this option seriously, because the fact that eel live in specific area, which we imply from the text does not necessarily mean the area is hospitable to them. it is very much possible that simply because of their tough fighting against nature's inconveniences eel are managing to live in New Guinea. EEl could survive that area, even the waters are not hospitable to them. U can not conclude that from the stem given.

@ykaiim

I agree to your explnation and to the OA 'D'.

But can you please give more explanation how can we eliminate E.

I thought I was the odd person to pick (D)

A new species of fish has just been discovered living in great numbers in the waters off Papua New Guinea. The fish exhibits some characteristics belonging to sharks, such as a cartilaginous skeleton. However, the fish also exhibits characteristics belonging to eels, such as a long, snake-like body. Because of the habitat where it was found and its obviously eel-like body, almost all scientists believe that the fish is an eel. But the cartilaginous skeleton puzzles them, since no known eel possesses one. So scientists are still unsure as to the fish's precise classification, but they agreed immediately that the most logical classification would be as either a shark or an eel.

The statements above, if true, most strongly support which of the following?

A. To be placed into a certain classification, a fish must possess all the characteristics of that classification. - We dont know this because the argument has no information.

B. Physical characteristics, such as skeletons, are scientists' primary means of classifying new species. - out of scope

C. Some fish with cartilaginous skeletons are not sharks. - out of scope. This looks tempting though because the author has used familiar words from the argument

D. The waters off Papua New Guinea are generally hospitable to eels. - argument says "Because of the habitat where it was found and its obviously eel-like body, almost all scientists believe that the fish is an eel" - correct

E. A fish cannot be both a shark and an eel. - Scientists agreed that the most logical classification would be either a shark or an eel but it has not be proved yet. So we cannot say that a fish cannot be both a shark and an eel
